LTC4009 LTC4009-1/LTC4009-2 applicaTions inForMaTion 10. If possible, place all the parts listed above on the same 12. For best current programming accuracy, provide a PCB layer. Kelvin connection from RSENSE to CSP and CSN. See 11. Copper fil s or pours are good for al power connections Figure 13 for an example. except as noted above in Rule 3. Copper planes on 13. It is important to minimize parasitic capacitance on multiple layers can also be used in parallel. This helps the CSP and CSN pins. The traces connecting these with thermal management and lowers trace inductance, pins to their respective resistors should be as short which further improves EMI performance. as possible.
